Which big screen super stud would win in a fight: Batman or Jason Bourne?

Access Hollywood's Shaun Robinson went straight to Ben Affleck and Matt Damon (who are playing Batman and Bourne, respectively, in upcoming movies) to get this very important question answered!

"Well, first of all, Batman is not real and Jason Bourne is," Matt told Shaun of the Caped Crusader versus the rogue CIA operative, in an exclusive sitdown with Matt and Ben Ã¢â¬â their first broadcast interview since announcing the winner of "Project Greenlight" Season 4.

Added Matt, "I don't understand why Batman and Superman are fighting. I guess I'll have to see the movie."

Faux-posturing aside, the duo said the changes that have taken place in their lives since "Project Greenlight" Season 3 aired nine years ago have informed their approach on Season 4.

Not only do both stars have children now (Ben has three with wife Jennifer Garner; Matt has four with wife Luciana), Ben is a respected director.

"I hadn't directed anything when we did the first 'Project Greenlight' Ã¢â¬â I've directed three movies since then, and it's only given me additional empathy for what directors go through," Ben said. "I know first-hand that the job is harder than I thought it was, I know that there are a lot more decisions than I recognized initially. But a lot of that just comes from getting older and doing more movies anyway. It's really hard. It's hard to make a movie that works."
